MDKSA-2007:012: kernel |

Check for the version of the kernel package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory MDKSA-2007:012 (kernel). Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel: The __block_prepate_write function in the 2.6 kernel before 2.6.13 does not properly clear buffers during certain error conditions, which permits users to read portions of files that have been unlinked (CVE-2006-4813). The clip_mkip function of the ATM subsystem in the 2.6 kernel permits remote attackers to dause a DoS (panic) via unknown vectors that cause the ATM subsystem to access the memory of socket buffers after they are freed (CVE-2006-4997). The NFS lockd in the 2.6 kernel before 2.6.16 permits remote attackers to cause a DoS (process crash) and deny access to NFS exports via unspecified vectors that trigger a kernel oops and a deadlock (CVE-2006-5158). The seqfile handling in the 2.6 kernel up to 2.6.18 permits local users to cause a DoS (hang or oops) via unspecified manipulations that trigger an infinite loop while searching for flowlabels (CVE-2006-5619). A missing call to init_timer() in the isdn_ppp code of the Linux kernel can permit remote attackers to send a special kind of PPP pakcet which may trigger a kernel oops (CVE-2006-5749). An integer overflow in the 2.6 kernel prior to 2.6.18.4 could permit a local user to execute arbitrary code via a large maxnum value in an ioctl request (CVE-2006-5751). A race condition in the ISO9660 filesystem handling could permit a local user to cause a DoS (infinite loop) by mounting a crafted ISO9660 filesystem containing malformed data structures (CVE-2006-5757). A vulnerability in the bluetooth support could permit for overwriting internal CMTP and CAPI data structures via malformed packets (CVE-2006-6106). The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels immediately and reboot to effect the fixes. In addition to these security fixes, other fixes have been included such as: - __bread oops fix - added e1000_ng (nineveh support) - added sata_svw (Broadcom SATA support) - added Marvell PATA chipset support - disabled mmconf on some broken hardware/BIOSes - use GENERICARCH and enable bigsmp apic model for tulsa machines To update your kernel, please follow the directions located at: http://www.mandriva.com/en/security/kernelupdate Solution : http://wwwnew.mandriva.com/security/advisories?name=MDKSA-2007:012 Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: This script is Copyright (C) 2007 Tenable Network Security |
